Abstract: 1. A trap for trapping and killing of small animals, like rats and mice, comprising a stand (1), a pivoting clamp means, journalled in the stand around a first axis (5), which clamp means can be strained against the action of a force means (4) like a spring, and which can be released by a releasing means from a first, loaded position, when an animal acts upon the releasing means, so that the clamp means substantially immediately swings, acted upon by the force means, to a second position, where it hits and kills the animal, the clamp means, extending from the first axis (5), being provided with a first (2) and a second (3) arm, a first fastening point (8) of said force means being provided at the end, that is turned from the first axis (5) of the first arm (2), the second fastening point (9) of the force means being provided at the stand, the force line between the two fastening points of the force means running through or in the vicinity of said first axis (5), so that the force means exerts no or just a minor torque in the direction towards the second position of the clamp means, when the clamp means is in its first position, characterized in that the releasing means is journalled around a second axis (7) in the stand, forming a first arm portion designed like a cap (6) above a vessel (12) for bait, and a second arm portion (10) acting upon the first arm (2) of the clamp means when the cap (6) is lifted by the animal. 2. A trap according to Claim 1, characterized in that the second arm portion (10) of the releasing means is provided with a securing member (11), that locks the first arm (2) of the clamp means when this is in its said first position, which securing member (11) releases the first arm (2) of the clamp member, when the cap (6) is lifted by the animal. 3. A trap according to Claim 1 characterized in that there is provided a stop device (l3) for preventing the clamp means from being turned to let the first arm (2) of the clamp means take a position in which the second arm portion (10) of the releasing means cannot act upon the first arm (2) of the clamp means. 4. A trap according to Claim 1, characterized in that there is provided guide means (14) for guiding small animals to the bait, preventing larger animals from acting upon the releasing means. 5. A trap according to Claim 1, characterized in that stand is designed with a portion (15) like a platform, extending backwards from the vessel (12). 6. A trap according to Claim 1, characterized in that the cap (6) and the vessel (12) are designed in such a way, that the bait is optically and from the smell, observable to the animal. 7. A trap according to Claim 1, characterized in that it is provided with an outer shell (16) into which the trap may be inserted to a protected position, which shell is provided with a first opening (17), with such a size and located in such a way, that it admits animals of a desired, maximum size access to the releasing device (6), and the shell (16) is provided with an elongated second opening (18) arranged in such a way, that a string (19) or the like may be led in through the second opening and releasably stretch the clamp means (3) to the first, loaded position.
